The crinoid is pentamerous in cross section – so I’m certain about that.  I had wondered about the wood inclusions – I’ll do some research on wood borers. Have you ever seen any in the literature? Thanks for the suggestion.

Nice pictures.

I know it is hard to tell from photographs - but - are you sure that
it is a crinoid and not an uncoiling ammonite; could the things in the
wood be boring bivalves?

I agree with you about the small scale stuff being fascinating - but
have now found that some of my microfossils are starting to get pyrite
rot.
